Researchers find high levels of pesticides in the Great Barrier Reef, including one that’s BANNED in 60 countries
Marine scientists have detected dangerous levels of several pesticides in the Great Barrier Reef, including the herbicide atrazine. This pesticide has been banned in 60 countries but remains registered for use in Australia. In a report published in the journal Estuarine, Coastal and Shelf Science, reef water quality expert Jon Brodie and fisheries veterinarian Matt Landos said that 50 individual pesticide […]

Study suggests the ice age was caused by global cooling after a giant asteroid collision in space
An international team of researchers suggests that a massive asteroid collision in space may have triggered the ice age 460 million years ago. In a study published in the journal Science Advances, the researchers said that the breakup of an enormous asteroid sent massive amounts of debris whirring through the solar system, shrouding Earth with a thick blanket […]

Chemical reaction between pipe alloy and water disinfectants produce cancer-causing chromium in drinking water
Researchers from the University of California, Riverside have found that pipe alloy can react with residual water disinfectants to produce cancer-causing chromium that gets mixed in drinking water. In a study published in the journal Environmental Science & Technology, the researchers said that chemical reactions can change chromium in water pipes into a form that creates genetic mutations in cells. […]

Volcanic eruption triggered worst mass extinction in Earth’s history – study
An international team of researchers has found further evidence that volcanic eruptions were responsible for the largest mass extinction event in history. In a study published in the journal Geology, the researchers detailed their discovery of coronene, a type of hydrocarbon that can be produced by an intense volcanic eruption, in sedimentary rocks. Link of coronene to volcanic eruptions […]

New diesel engine boasts low consumption and high efficiency, decreasing emissions of contaminating particles by 80%
European researchers have developed an improved diesel engine that’s more eco-friendly and efficient than current models, paving the way for greener and fuel-efficient vehicles. During a project meeting held in Austria, the researchers said that the new engine uses less fuel and emits 80 percent fewer contaminating particles than the current legal limits. Developing eco-friendly, efficient diesel engine The DiePeR project was […]

Caterpillar wears tower of its own molted heads to fend off predators
A caterpillar called the gum-leaf skeletonizer makes a tall hat out of its discarded heads to ward off predators. This two-centimeter Australian catterpillar is known for stacking its molted heads instead of discarding them. This creates a horn-like structure that protects the caterpillar from stink bugs and other predators. The creature has the scientific name of Uraba lugens and is also called the […]

North Atlantic right whales “whisper” to protect young calves from predators
A recent study published in Biology Letters found that North Atlantic right whales produce “whisper-like sounds” when communicating with their calves to avoid attracting predators. Researchers from Syracuse University, Duke University and the National Oceanic and Atmospheric Administration observed that the mothers dramatically toned down an “up call,” which right whales use to communicate with each other, when communicating to their young. […]

Scientists develop new material that captures CO2 and turns it into “useful organic chemicals”
Researchers from Japan and China have developed a new material that can suck carbon dioxide out of the air and convert it into organic matter. The material works as a “molecular” sieve and selectively captures carbon dioxide molecules As reported in a paper published in the journal Nature Communications, carbon dioxide that’s caught in the material can be transformed into an organic substance […]

The language of Nature: Plants communicate with each other to send alerts about incoming pests
When they’re under attack, plants send warning signals, says a recent study published in Current Biology. These signals come in the form of airborne natural chemicals, called volatile organic compounds (VOCs), which alert neighboring plants to a threat. But this is not merely an altruistic act, suggested researchers. It’s mutually beneficial as the receiving plants also emit these […]

Human evolution occurred in ecosystems vastly different than those found today, suggest researchers
A recent study published in the journal Proceedings of the National Academy of Sciences suggests that humans emerged from ecosystems that were markedly different from those inhabited by modern humans. Researchers from the University of Utah, the University of Massachusetts, Amherst (UMass Amherst) and Colorado State University examined fossil records of mammal communities dating back as far as seven million […]
